To solve this, take a look at the images provided and first find out the number of polygons out of the total number of cards given which would be 3 polygons out of 5 cards, which would be better represented as the fraction 3/5. Now, the question asks to find the probability of Julie picking a card that shows a polygon, and since 3 out of 5 of the cards are polygons, your answer would be 3/5.

Answer:

x = 16

Step-by-step explanation:

Corresponding sides are proportional.

BE/CD = AE/AD

20/(3x+8) = (x-1)/(x-1+27)

20(x+26) = (3x+8)(x -1)

In standard form, this is ...

3x^2 -15x -528 = 0

x^2 -5x -176 = 0 . . . . . . divide by 3

(x -16)(x +11) = 0 . . . . . . . factor

x = 16

This is the positive value that makes the product zero. x=-11 will also make the product 0, but gives negative segment lengths in the geometry. It is an extraneous solution.
